LADLE HANGER;

Application filed .Tune 30, 1921.. Serial No. 481,677. I

To all whom it may concern:

Be it known that citizen of the United States, residing at Hoquiam, in the county of Grays Harbor and State of Washington, and ALBERT E. (lrREENE, a. citizen of the United States, rosiding at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Ladle Hangers, of Which the following is a specification.

This invention relates to ladle hangers, and is an attachment for tilting furnaces designed to hold ladles and is more particularly intended for use of electric The object of our invention is to fill ladies with molten metal while the ladle hangs in a suitable hanger attached to the furnace. Y

The invention consists in, one modifica tion of a pair of frames which may be attached to the furnace shell or spout and adapted to the ladle may be held in posit-ion with relation to the spout of the furnace so that on tilting the furnace over the metal will enter the ladle and on filling of the ladle the furnace may be tipped back until the metal stream stops and their the ladle may be taken away for pouring themolten metal. In another modification hangers are hung on supporting brackets so as to always hang in a vertical position when the furnace is tilted. Heretofore it has been customary for two men to hold the ladle in a shank in front of the furnace while the metal is poured into the ladle, This practise results in spilling the metal and is dangerous on account of the sparks and particles of molten metal which may spatter and burn the workmen. The purpose: of this invention is to provide a means of holding the ladle in position under the spout of the furnace in such manner-that the stream of metal will enter the ladle irrespective of the position of the furnace whether it be tilted over or in the normal position.

One feature providing suitable slots in the fixed frame which supports the shanks of the ladle whereby the ladle may beheld. in front of the spout.

of this invention consists in vides special shaped slots in which the ladle shanks ping over and spilling the metal.

In another modification this invention provides means of varying the position'of the hanging members: which hold the ladle shank, whereby ladles of rest to prevent the ladle from tip varying diameters may be used in the same hanger and wheres by the position of the ladle with respect'rto. the end of the spout may cordance with the position which the metal" stream takes on leaving the spout.

Another feature. of our invention relates to construction of the which are attached to the furnace shell .or to brackets fixedly connected thereto and another feature. relates to notches provided for varving the position of either the ladle shank on the fixed members or for varying the position of a slottedhanging member which latter member may hold the ladle shank.

Another feature of our invention is the construction of the hanging members. These and other features of the invention will be better understood with reference to the drawings.

The ladle hanger shown in Fig. 1 is shown as attached to a; furnace mounted on trunnions.

R f ing to Figs. 1 and 2, 1 is theshe'll The of the top of the I means of bolts 5. In these figures these frame members 4:, 4 consist of structural steel angle irons. Attached to each of these a'ngle irons 4, f is a notched member 6 supportedby any suitable construction such as the piece )5 which holds the members 6 in outward relation from the furnace shell. Notches 8. 9 and 10 are provided in the members 6 and are designed to hold the shanks 11 of the ladle. The ladle 12 is shown in position underneath the spout ready to take the stream of molten metal when the furnace is tilted over. In this modification of ladle hanger the ladle may be held upright by the workman keeping his hand on the end of the ladle shank to keep the ladle in vertical position while the furnace is tipped over. The notches 8, 9 and 10 are made round whereby the ladle may be tilted by turning the shank. Tn another modification of this invention described further on a special shaped slot is provided in a separate member whereby the ladle is prevented from tipping over while held in the slot. On tipping the furnace shown in Figs. 1 and 2, the stream of metal enters the ladle and when the ladle is sufficiently full the furnace is tipped back and the pouring discontinued. The ladle may then be taken away for pouring its contents into suitable molds.

Referring to Figs. 3 and i a. furnace of the rolling cylinder type is shown. Attached to the spout of this furnace are two notched members 23. These members are attached to the spout 22 of the furnace 21 by means of bolts whereby they may be quickly removed in case it is desired to have them out of the way when a crane ladle or other type of ladle is used. However. these extensions can be cast as a part of the ladle spout if desired. The side view of these members 23 is shown in Fig. 3. Fig. 4 shows these members 23 from the front where it is seen'that the parts of the members 23 which extend outwardly from the furnace spout are also provided with an extension whereby the notched portion of these members are at a greater distance apart than the width of thespout at the place where these members arebolted or attached to the spout. This construction is intended to keep the slotted members 26 which hang in the notches of the members 23 far enough away from the ladle so that in case slag or metal spills over it will not enter the slots of the members 26 and will therefore not interfere with the holding or removing of the ladle shank from. the slotted member. The slotted members 26 consist of suitable pieces of steel or other sufficiently strong metal to support the weightof the filled ladle. The slots 27, 30 and 31 are provided so that the ladle may be hung at. whatever elevation is desired and so that ladles of diderent sizes may be conveniently used. Any suitable number of improvement in the notches in the members 23 and slots in the members 26 may be provided. I prefer to make the members 23 and 26 of cast steel for the purpose of ample strength. A'piece of iron or steel'rod bent to suitable shape to go over the member 23 and rest in the notches thereof may be cast into the member 26 so as to form a loop or link which serves to hold the slotted member 26 in the notched member 23.

The dotted lines 32 in Fig. 3 and the numerals 29 22 and 26 show the position of the ladle and spout and ladle hanger, the metal stream 32 entering the-ladle when the furnace is rolled over for the purpose of pouring.

The slots in the members 26 are shown as elongated and Fig. 3 shows the ladle shank in section taken through the center of one of the slots of the members 26 and the shank of the ladle is flattened to prevent the ladle from tipping over.

When pouring in hand ladles in what is ordinarily known as a one man shank the shank may be held on one side of the ladle hanger, that is in one of the slotted members 6 or 26.

This invention results in very material pouring of metals especially steel and brass for it is possible to fill the ladle without danger to the workmen holding the shanks and the pouring may be completed without the workman touching the ladle shank where this is desired. possible for a furnace to be operated by a very much smaller crew than has usually been required heretofore. The furnace man can tilt the furnace and fill the ladle and then tilt the furnace back and then assist his helper in pouring the ladle full of metal. It is also found that a very great saving of metal results because the operators are not afraid from the spattering of the stream of metal.

What we claim is 1. A ladle hanger for a tilting furnace comprising a frame attached to the furnace and provided with a slotted memberadapt ed to support the shank of a ladle whereby the ladle may be supported in a position to catch the metal stream from the furnace spout as thefurnace tips over.

2. A ladle hanger comprising two notched members attached to the spout of the furnace and extending outwardly from the furnace shell and provided with notches at various distances from the end of the furnace spout adapted to suppor' a hanging member in said notches; and said hanging member having suitable slots for holding the shanks of a ladle shank in position under the spout of the furnace.
